Wrist-top instrument



FIG. 1 is an upper, left side perspective view of a wrist-top instrument;

FIG. 2 is a top view of the wrist-top instrument of FIG. 1;

FIG. 3 is a enlarged lower perspective view of a region of the wrist-top instrument of FIG. 4; and,

FIG. 4 is a lower, right side perspective view of the wrist-top instrument of FIG. 1.

The ornamental design that is claimed is shown in solid lines in the drawings. The jagged broken lines in FIGS. 3 and 4, which are located around the U-shaped indentation on the bottom of the wrist-top instrument are used to show the unclaimed boundary of the portion of the design that is shown in the enlarged fragmentary view. The other broken lines in the drawings, such as the broken lines showing a wrist band, are included for the purpose of illustrating environmental elements only and form no part of the claimed design. 

I claim the ornamental design for a wrist-top instrument, as shown and described.
